Looking to convert your ¾ ton Truck to ½ ton front suspension? We are proud to introduce the onlyC-20 to C-10 2½" Drop Spindles available on the market. (disc brakes required). Over the years, we’ve had many customers with C-20 8-lug Trucks that would like to convert over to the better riding C-10 suspension and change their wheels to either a 5-lug or 6-lug bolt pattern.
